前情回顾
之前我们设计了权限模型并提交了数据库脚本，然后通过 mingyue-common-gen 模块 MingYueCommonGenDemo 生成了基础代码，接下来我们需要提供两个关键接口：
- 获取用户权限信息；
- 获取用户路由信息；
TIPS
为了严格按照 RESTful 接口风格设计，变更现有接口命名： getSysUserInfoByUsername => userInfo、getSysUsers => list，后续接口也将严格按照 RESTful 接口风格设计。
登录缓存用户信息
Session 会话
Session 是会话中专业的数据缓存组件，通过 Session 我们可以很方便的缓存一些高频读写数据，提高程序性能，例如：
// 在登录时缓存 user 对象
StpUtil.getSession().set("user", user);// 然后我们就可以在任意处使用这个 user 对象
SysUser user = (SysUser) StpUtil.getSession().get("user");
在 Sa-Token 中，Session 分为三种，分别是：
Account-Session: 指的是框架为每个账号 id 分配的 SessionToken-Session: 指的是框架为每个 token 分配的 SessionCustom-Session: 指的是以一个特定的值作为 SessionId，来分配的 Session
Token-Session
缓存用户信息
public static void login(SysUser userInfo) {// 请求作用域：存储的数据只在一次请求内有效，请求结束后数据自动清除。SaStorage storage = SaHolder.getStorage();storage.set(LOGIN_USER_KEY, userInfo);storage.set(USER_KEY, userInfo.getUserId());// 第1步，先登录上StpUtil.login(userInfo.getUserId());// 第3步，缓存用户信息StpUtil.getTokenSession().set(LOGIN_USER_KEY, userInfo);
}
获取用户信息
public static SysUser getLoginUser() {SysUser loginUser = (SysUser) SaHolder.getStorage().get(LOGIN_USER_KEY);if (loginUser != null) {return loginUser;}loginUser = (SysUser) StpUtil.getTokenSession().get(LOGIN_USER_KEY);SaHolder.getStorage().set(LOGIN_USER_KEY, loginUser);return loginUser;
}
接口测试
@GetMapping("info")
@Operation(summary = "获取当前用户全部信息")
public R<SysUser> userInfo() {SysUser sysUser = LoginHelper.getLoginUser();System.out.println("=============================");System.out.println(JSONUtil.toJsonStr(sysUser));System.out.println("=============================");return R.ok(null);
}
接口调用打印如下：
=============================
{"userId":1,"username":"mingyue","nickname":"明月","sex":"0","password":"123456","phone":"13288888888","status":"0","isDeleted":"0","createTime":1689757582000,"updateTime":1689757585000,"createBy":"mingyue","updateBy":"mingyue"}
=============================
获取用户权限信息
接口层
@GetMapping("info")
@Operation(summary = "获取当前登录用户全部信息")
public R<UserInfoVo> userInfo() {return R.ok(sysUserService.getUserInfo());
}
业务层
@Override
public UserInfoVo getUserInfo() {UserInfoVo result = new UserInfoVo();SysUser sysUser = LoginHelper.getLoginUser();// 密码置空sysUser.setPassword(null);result.setSysUser(sysUser);// 设置角色列表Set<String> rolePermission = sysRoleService.getRolePermission(sysUser.getUserId());result.setRoles(rolePermission);// 设置权限列表Set<String> menuPermission = sysMenuService.getMenuPermission(sysUser.getUserId());result.setRoles(menuPermission);return result;
}
测试接口
Authorization Token 通过登录接口获取
curl -X 'GET' \
'http://mingyue-gateway:9100/system/sysUser/info' \
-H 'accept: */*' \
-H 'Authorization: vXPJnADIcTPfKuP3reBYmmUAi4xjw8nf'
接口返回
{"code": 200,"msg": "操作成功","data": {"sysUser": {"userId": 1,"username": "mingyue","nickname": "明月","sex": "0","password": null,"phone": "13288888888","email": null,"avatar": null,"status": "0","isDeleted": "0","createTime": "2023-07-19T17:06:22","updateTime": "2023-07-19T17:06:25","createBy": "mingyue","updateBy": "mingyue"},"permissions": null,"roles": [null,"system:user:list"]}
}
获取用户路由信息
接口层
@GetMapping("getRouters")
@Operation(summary = "获取路由信息")
public R<List<RouterVo>> getRouters() {Long userId = LoginHelper.getLoginUser().getUserId();return R.ok(sysMenuService.getRouters(userId));
}
业务层
@Override
public List<RouterVo> getRouters(Long userId) {List<SysMenu> sysMenus = sysMenuMapper.selectMenuTreeByUserId(userId);return this.recursionMenu(sysMenus, -1L);
}/*** 递归菜单，构建菜单树*/
private List<RouterVo> recursionMenu(List<SysMenu> sysMenus, Long pid) {List<RouterVo> tree = CollUtil.newArrayList();for (SysMenu menu : sysMenus) {if (menu.getParentId().equals(pid)) {RouterVo router = new RouterVo();router.setPath("/" + menu.getPath());router.setName(menu.getPath());router.setComponent(menu.getComponent());router.setRedirect(menu.getRedirect());MetaVo metaVo = new MetaVo();metaVo.setTitle(menu.getMenuName());metaVo.setIsLink(menu.getIsLink());metaVo.setIsHide(UserConstants.IS_HIDE.equals(menu.getIsHide()));metaVo.setIsKeepAlive(UserConstants.IS_KEEP_ALIVE.equals(menu.getIsKeepAlive()));metaVo.setIsAffix(UserConstants.IS_AFFIX.equals(menu.getIsAffix()));metaVo.setIsIframe(UserConstants.IS_IFRAME.equals(menu.getIsIframe()));metaVo.setIcon(menu.getIcon());router.setMeta(metaVo);router.setChildren(recursionMenu(sysMenus, menu.getMenuId()));tree.add(router);}}return tree;
}
测试接口
curl -X 'GET' \
'http://mingyue-gateway:9100/system/sysMenu/getRouters' \
-H 'accept: */*'
-H 'Authorization: vXPJnADIcTPfKuP3reBYmmUAi4xjw8nf'
接口返回
{"code": 200,"msg": "操作成功","data": [{"path": "/system","name": "system","component": null,"redirect": null,"meta": {"title": "系统管理","isLink": "0","isHide": false,"isKeepAlive": false,"isAffix": false,"isIframe": false,"icon": "iconfont icon-xitongshezhi"},"children": [{"path": "/user","name": "user","component": "/system/user","redirect": null,"meta": {"title": "用户管理","isLink": "0","isHide": false,"isKeepAlive": false,"isAffix": false,"isIframe": false,"icon": "iconfont icon-icon-"},"children": []},...]}]
}
小结
现在用户已经拿到权限点了，接下来整合一下权限点与 Sa-Token 的使用，看看 Sa-Token 如何通过权限点控制接口访问。
